jQuery Traversing Siblings

This tutorial will educate you on navigating horizontally within a DOM tree using jQuery.

In logical relationships, siblings are elements that share the same parent.

jQuery offers several methods, including siblings(), next(), nextAll(), nextUntil(), prev(), prevAll(), and prevUntil() which enable you to navigate horizontally within the DOM tree.

The jQuery siblings() method is used to select all the sibling elements of the selected element(s) in the DOM. Sibling elements are elements that share the same parent in the HTML structure. This method allows you to find and manipulate elements that are on the same level or have the same parent as the selected element(s). Here is a basic syntax:

$(selector).siblings([filter])

• selector: An optional parameter that specifies a filter for selecting specific sibling elements.
• filter: An optional parameter that further refines the selection of sibling elements based on specific criteria.

The following example will add the class .highlight to the siblings of the <p> element, which are the <h1> and <ul> elements, on document load.

<style>
    .highlight{
        background: purple;
    }        
</style>

<script>
    $(document).ready(function () {
        $("p").siblings().addClass("highlight");
    });
</script>

<div class="container">
    <h1>Happy Morning</h1>
    <p>Here is an<em> uncomplicated paragraph</em>.</p>
    <ul>
        <li>List One</li>
        <li>List Two</li>
    </ul>
</div>

• Try this code

You can include one or more selectors as parameters within the siblings() method to filter your search for specific siblings. The following example will apply a border only around the siblings of the <p> element that are <ul> elements.

$("p").siblings("ul").addClass("highlight");

• Try this code

The jQuery next() method is used to select the immediately following sibling element of the selected element(s) in the DOM. It allows you to navigate to the next sibling element, which shares the same parent as the selected element(s).

The following example will add a highlight to the next sibling of the <p> element, which is the <ul> element.

$("p").next().addClass("highlight");

• Try this code

The jQuery nextAll() method is used to select all the sibling elements that come after the selected element(s) in the DOM hierarchy. It allows you to target and manipulate all the following sibling elements of the selected element(s) that share the same parent.

In this example, the .highlight class is added to all the following siblings of the <p> element that comes after it in the DOM structure.

$("p").nextAll().addClass("highlight");

• Try this code

The jQuery nextUntil() method is used to select all the sibling elements that come after the selected element(s) in the DOM hierarchy up to, but not including, a specified element or elements. It allows you to target and manipulate sibling elements up to a certain point in the DOM.

In simpler terms, you can think of the jQuery nextUntil() method as a way to select and collect all the sibling elements that appear between two specified elements in a DOM hierarchy. It doesn't include the starting and stopping elements themselves, focusing only on what's in between.

$(selector).nextUntil(stopSelector, filter)

• selector: Specifies the elements to begin the selection from.
• stopSelector: Specifies the element(s) up to which the selection should go, but not including the element(s).
• filter: An optional parameter that further refines the selection of following sibling elements based on specific criteria.

In this example, the .highlight class is added to all the following sibling elements of the <h1> element, but it stops before reaching the <ul> element.

$("h1").nextUntil("ul").addClass("highlight");

• Try this code

The jQuery prev() method is used to select the immediately preceding sibling element of the selected element(s) in the DOM. It allows you to navigate to the previous sibling element, which shares the same parent as the selected element(s).

In this example, the .highlight class is added to the previous sibling of the <ul> element, which is the <p> element.

$("ul").prev().addClass("highlight");

• Try this code

The jQuery prevAll() method is used to select all the preceding sibling elements that come before the selected element(s) in the DOM hierarchy. It allows you to target and manipulate all the preceding sibling elements of the selected element(s) that share the same parent.

In this example, the .highlight class is added to all the preceding siblings of the <ul> element, which are the <p> elements.

$("ul").prevAll().addClass("highlight");

• Try this code

The jQuery prevUntil() method is employed to retrieve all the preceding sibling elements up to, but not including, the element that matches the specified selector. In simpler terms, it returns all the preceding sibling elements positioned between two specified elements within a DOM hierarchy.

Here's an example illustrating how to highlight all the preceding sibling elements of the <ul> element while excluding the <h1> element, effectively highlighting both <p> elements:

$("ul").prevUntil("h1").addClass("highlight");

Can you chain multiple next() methods together to select multiple next siblings?

Yes, you can chain multiple next() methods to select multiple consecutive next siblings. For example, $(selector).next().next() will select the second next sibling.

How can you use the next() method with animations or transitions?

You can use the next() method in combination with jQuery's animation or transition functions to apply animations to the selected next element. For example, $(selector).next().slideUp() will slide up the next element.

Is the order of elements returned by nextAll() the same as the order in the DOM?

Yes, the nextAll() method returns elements in the same order as they appear in the DOM, from the immediate next sibling to the last one.

How can you select and manipulate multiple next siblings using nextAll()?

Sibling Element Navigation in jQuery equips developers with a versatile toolkit for exploring and manipulating elements within the Document Object Model (DOM). With the ability to efficiently select Adjacent Elements and navigate to Nearby Elements, it streamlines the process of targeting elements in proximity. The Sibling Element Search feature empowers precise exploration of neighboring nodes, while Immediate Neighbor Retrieval simplifies access to the closest sibling elements. Closest Sibling Element selection enhances the efficiency of element interactions by enabling quick access to the nearest elements.

This functionality extends to both forward and backward DOM navigation, allowing developers to perform sequential searches for elements in adjacent positions. Forward DOM Navigation, which includes Next Element Navigation and Next Sibling Selection, facilitates efficient movement in the forward direction. It enriches element selection and interaction by providing precise and rapid access to elements. Furthermore, Backward Sibling Selection, involving Previous Element Navigation and Previous DOM Navigation, offers the means to navigate the DOM in the reverse direction.

jQuery's Next Element Navigation and Next Sibling Selection features provide developers with efficient tools for navigating and interacting with elements within the Document Object Model (DOM). These methods enable sequential element searches and simplify forward DOM navigation. With Next Element Navigation, developers can quickly and precisely access the next elements in the DOM hierarchy, enhancing the interaction with their web applications.

On the other hand, Previous Element Navigation and Backward Sibling Selection allow reverse DOM navigation, enabling developers to navigate and interact with elements in the reverse direction. This comprehensive approach to navigating the DOM, both forward and backward, empowers developers to create dynamic and interactive web applications efficiently.
